# To build this image and run it with a shell, first change into the directory
# where this Dockerfile lives, then:
#
# sudo docker build -t pv-v5.6.0-egl .
#
# Or, to choose a different version:
#
# sudo docker build --build-arg PARAVIEW_TAG=master --build-arg SUPERBUILD_TAG=master -t pv-master-egl .
#
# Run the image with bash to look around:
#
# sudo docker run --runtime=nvidia -ti pv-v5.6.0-egl bash
